TurboTax gives you an estimated date for receiving your refund based on a 21 day average from your date of acceptance, but it can take longer.

Why havent I received an email from turbotax saying my returns have been submitted?
If you are using the online version, the screen will congratulate you for submitting your return. As long as you pressed, "transmit my returns now" and it it said "you did it," then it has been submitted. You will get an email telling you that your tax returns have either been accepted or rejected.
I have submitted my tax return 2 times this year the 1st time it took 72 hours to get a rejection and now it's been almost 48 hours and still no approval. The IRS also still doesn't have my tax forms... Why hasn't my forms been submitted?
Pending means your e-filed return is on its way and the government hasn't accepted or rejected it yet. Please see What does pending mean? for more detailed information.
